Hi;
First many thanks to the author for providing the free volumes Lessons in Electric Circuits.
Now in reference to the book Lessons in Electric Circuits Volume II AC Chapter 5 on the HTML version.
I think I found a typographical error on the first table Impeadance Z of inductor L in Polar notacion should be 245.04 Ð 90 and it has 254.04 Ð 90. Also on the 8 tables bellow you can find the same error, but the results calculations are correct.
Sincerely,
Miguel Rodriguez Yepes.
